A reactor with a preheating device

Abstract

The invention is a reaction kettle with a preheating device. By setting a reaction chamber and a material storage chamber, the initial reaction material is passed into the reaction chamber to react first. After the reaction reaches a certain level, the material A The gas generated by reacting with material B is passed into the ventilation preheating device, that is, the gas flow through the initial reaction can preheat the material to be reacted, and at the same time, the gas flow after heat exchange is flowed into the air bag to inflate the air bag. After the air bag is inflated to a certain extent, touch the switch to inflate the material storage box, so that the material in the storage box is rushed out of the discharge pipe by the airflow and enters the reaction chamber, which is convenient to control the reaction degree of the reaction chamber and automatically carry out the reaction to a certain degree The reaction chamber is fed.

Description

technical field [0001] The invention relates to the technical field of reaction kettles, in particular to a reaction kettle with a preheating device. Background technique [0002] The reaction kettle generally has a preheating and heating process during the reaction. According to the heating method, it can be divided into electric heating, hot water heating, heat transfer oil circulating heating, far-infrared heating, outer coil heating, etc.; its scope of application is suitable for petroleum, chemical industry , medicine, metallurgy, scientific research, colleges and universities and other departments to carry out high temperature and high pressure chemical reaction experiments to complete hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, polymerization, condensation, heating and mixing, constant temperature reaction, etc. The technical process, the existing reaction kettle reaction process has the situation of staged reaction,...

AI Technical Summary

Problems solved by technology

Through the cooperation of the negative pressure pipe and the feeding pipe, the material is sucked into it by the feeding tank in the negative pressure state; it can be seen that the feeding method in the prior art often requires a feeding device outside the valve body, and the timing and timing of feeding The quantity is not easy to control, and it is not possible to add materials in time during the reaction, nor can it preheat the added materials
